A technique facilitates perforating operations. According to an embodiment, a perforating gun system utilizes a plurality of modular perforating gun sections which are readily assembled to create a perforating gun with a desired number and orientation of shaped charge holders. In some applications, the modular perforating gun sections may be formed of plastic, e.g. injection moldable plastic, to further reduce costs and provide great flexibility with respect to construction of the desired perforating gun.

A perforating gun assembly that orients one or more shaped charges within a well includes a housing and an orienting internal assembly configured to be disposed within a longitudinal bore of the housing. The orienting internal assembly may include at least one shaped charge holder or charge tube, a rotation support system, a detonator holder and/or a detonator. The rotation support system may be configured so that the detonator holder and/or detonator rotate together as a whole with the at least one shaped charge holder or charge tube. The rotation support system may include at least one bearing assembly, a plurality of rollers, or combinations thereof. The orienting internal assembly may be configured for gravitational orientation.

An improved perforating gun system. The perforating gun system includes a perforating gun having a shaped charge positioning tube that is securely received within a female opening in a tandem to provide a 360-degree connection to ground. The shaped charge positioning tube includes segmented end portions that extend over first and second contact housings. Each contact housing includes a contact pin that is biased outwardly by a spring, the spring comprising a portion of an electrical path for a firing signal.
